N.J. Admin. Code § 5:21-4.3 - Curbs or curbs and gutters
(a) Curbs or curbs and
gutters shall be used for drainage purposes, safety, and delineation and protection
of pavement edge. Where, based on stormwater management system design, there is
determined to be a problem with runoff, curbs or curbs and gutters shall be
used.
(b) Curb requirements shall vary
according to street hierarchy and intensity of development, in accordance with the
requirements set forth in Table 4.3 in
5:21-4.2. Generally, curbs shall be
required on streets with on-street parking.
(c) Where curbing is not required, edge definition
and stabilization shall be furnished for safety reasons, and to prevent pavement
unraveling. Curbing may be required for: stormwater management, road stabilization,
delineation of parking areas, 10 feet on each side of drainage inlets,
intersections, corners, and tight radii.
(d) Curb requirements may be waived by the
appropriate municipal approving agency, and shoulders and/or drainage swales used
when it can be shown that: shoulders are required by CAFRA; soil and/or topography
make the use of shoulders and/or drainage swales preferable; and/or the community
desires to preserve its rural character by using shoulders and/or drainage swales
instead of curbs. In cases of medium development intensity, the curbing requirement
may be waived where front setbacks exceed 40 feet and it can be demonstrated that
sufficient on-site parking exists.
(e) A
municipality may designate a curb type by ordinance. Where curb type is not
established by municipal ordinance, flexibility regarding curb type shall be
permitted as long as the curb type accommodates the system of drainage proposed.
Generally, curbs should be constructed of concrete or granite block. Curbing
materials shall accommodate the purposes set forth in (c) above.
(f) Curbs shall be constructed according to the
specifications set forth in
5:21-4.17.
(g) Curbing shall be designed to provide a curb
ramp in compliance with the Americans with Disabilities Act or the Barrier Free
Subcode of the New Jersey Uniform Construction Code (N.J.A.C. 5:23-7 ) at street
intersections, as applicable.
(h) Where
curbs and gutters are used and where the street is part of a designated bike route
as indicated in the bicycle circulation part of the municipal master plan, the
municipality may require that the cartway width be increased by one foot on each
side of a street that uses a curb and gutter.
